Specification of Letters Patent.

Patented May 12, 1908. Renewed Septeniber 25, 1907. Serial No; 39%,57'7.

To alt 'itlltl'ilt it may renew-11.:

Be it known that l. Jason .llrnnennu, a

citizen of the United States, residing at Pluhulelphia, m the county ofPhiladelphiavsnia. have invented uset'ul im n'ovements in o1" which thefollowing is and ritate ot Pennsyl certain new and liraiding ldachmes, a'specilication.

This invention relates to that class of braiding machines wherein twosets of tbreatl-supplying (ltYlt'telllP rotated in concentr annularpaths and in opposite directions to each other, and wherein the threadsol' one set are directed over and under the threads of the other set ina manner to Client the braiding operation, such for example as thatshown and described in .Letters Patent ol the l nited States No.(395,746 dated .ilarch its, 1902 to which reference may be had.

The object of this ii ivention is to provide machines of this characterwith means for introducing an additional thread or threads and directingthe latter, by tixed guides, toward the braiding point, between thepaths traversed by the th ads delivered from, the two sets of rotatingthread-sit lplying de vices, whereby a braid having straightlongitudinal threads ir .erwoven with the braided threads may beprmluced, as will be hereinafter fully described and claimed.

in the drawiiigs l igure 1 is a plan view of a portionot' a braidingmachine provided with my invention. Fig. 2 is a vertical sectionthereof, as on the line 2 2 of Fig. 1. Fig. 3 is a similar section, ason the line 3-- 3 of Fig. 1, showing the parts moved to bring one oi thethread guiding devices to this line. Fig. 4 is a sectional developmentof a on which the upper bobbin carriers run, and adjuncts, line 4 d ofFi 2.

l is the bed plate oi the machine from which projects a.centrelly-arranged hollow tubular post Fitted to this post 5 is a freelyrotatable wheel ti which carries a set oi threatl-supplying bobbins 7.The huh 8 ol' the wheel (3 is provided with a bevel gear wheel l) which.coacts with a similar wheel 10 on the driving shaft 11, by means ofwhichthe wheel 6 is positively rotated. The wheel (lcarries a series ofsuitalily-arrangerl. guide devices l2 whieh direct the threads from theas seen bobbins 7 toward the braiding point 13, and, at the same time,raise and lower the said threads during their rotary travel.

In the present instance, the guide devices 12 comprise gear wheels 14which are rotatably mounted on studs 15 proiecting from brackets 16 onthe wheel 6. The wheels 14 are provided with arms 17 carrying threadguiding eyes 18, and they mesh with and are rotated by a lixed gear ring19 supported by l. ra0l ets I20 projecting from a stationary frame 21which is supported by the post 5 above the wheel 6. The threads 22 passfrom the bobbins 7 through central perforas tions in the studs 15, and.then through the eyes 18 to the braiding pointlil; to the end that, asthe wheel 6 is actuated, the gear wheels '14 will be rotated, and theirrotating arms 17 will raise and lower the threads .22 during theironward travel, thereby causing the threads 22 to pass between and overand under the bobbins 28 and thus ell'ect the braiding operation, as iswell known inv this art.

The stationary frame 2! is provided with a tlange 24- which supports anannular tract:- way 25 on which the upper bobbin or thread carriers 26run in a direction reversely to the bobbins 7. The threads .37 l'rombobbins 28 carried, by the carriers 26 are led direct to the braidingpoint 3. The carriers 26 are driven by a series of pinions 239 which arerotatably mounted on the flange 24 of the stationary frame 21 and whichmesh with teeth 30 on the carriers 36, the pinions 29 being actuated bya gear the wheel 6.

By the t'oregoii'ig description it will be seen that the two sets ofbobbins 7 and 3. are supported and rotated in annular paths and inopposite directions to each. other: and that the threads 22 from thebobbins 7 are direrted, by the guide devices l2.

thereby producing braid in the usual manner. Thus far the machine is ofwell known construction and needs no detailed dei-zcription herein.

I desire it to be understood that i do not mechanism above deissubstantially the same as described in the patentherel to, as anysuitable means limit mysell' to the scribed which that shown andinbel'ore rel'erriu ring .31 carried by.
